Definitions

  • the present invention relates to a discharge container for discharging contents onto a discharge surface.
  • Priority is claimed on Japanese Patent Applications No. 2015-253536, filed December 25, 2015 , No. 2015-254159, filed December 25, 2015 , and No. 2016-192553, filed September 30, 2016 .
  • a discharge container as shown in the following Patent Document 1 includes a container main body in which contents are stored, a discharger having a stem capable of discharging contents by moving downward with respect to the container main body, a fixing member attached to a mouth portion of the container main body, and a movable member provided at the fixing member to be movable downward and having a discharge hole for discharging the contents discharged by the stem.
  • the movable member includes a locking portion that is locked to the stem and moves down the stem as the movable member moves downward.
  • the movable member is locked to the fixing member in a state in which the locking portion moves down the stem. Therefore, the contents can be continuously discharged from the discharge hole.
  • a discharge container as shown in the following Patent Document 2 has a saucer that stores liquid (contents) suctioned up above an internal piston.
  • a communication hole communicating with the internal piston and a receiving plate located above the communication hole are provided in the saucer.
  • the receiving plate is connected to a circumferential edge of the communication hole via a plurality of fixing legs provided at intervals in a circumferential direction of the communication hole.
  • a liquid outlet hole which discharges the liquid suctioned up above the internal piston to an upper surface (discharge surface) of the saucer is formed between adjacent fixed legs in the circumferential direction.
  • a plurality of liquid outlet holes are formed to be separated from each other in the circumferential direction by the plurality of fixed legs.
  • the discharge container includes a container body in which contents are stored, a discharger having a stem provided upright to be movable downward in a state where the stem is pushed upward, an exterior portion having a shaping surface and a plurality of molding holes, and an inner plate provided in the exterior portion to be vertically movable, and when the inner plate moves down with respect to the exterior portion, a diffusion chamber is formed between the inner plate and the exterior portion. Then, a plurality of shaped pieces are formed by the contents diffusing from the stem into the diffusion chamber and then the contents being discharged through the plurality of molding holes to the shaping surface, and a molded object can be formed by combining the respective shaped pieces.
  • GB 2220989A and US 5385303A patent each discloses a discharge container as claimed in the preamble of main claim 1.
  • Patent Document 3 discloses a constitution in which the exterior portion and the inner plate are provided to be integrally rotatable about a container axis and are moved down integrally by rotating them. Due to such a constitution, it is possible to improve the operability.
  • the inner plate is then moved up with a time lag, and additional contents in the diffusion chamber are discharged onto the shaping surface. Accordingly, the flow of the contents discharged from the molding holes becomes discontinuous, and thus the accuracy of the shape of the molded object may decrease.
  • Patent Document 3 discloses a constitution in which the inner plate is disposed to be movable downward in a state where the inner plate is pushed upward and the inner plate is directly pushed down. Due to such a constitution, the discharge of contents from the stem is stopped by stopping pushing down the inner plate, and the inner plate itself is moved up by an upward pushing force, and thus the contents in the diffusion chamber are discharged onto the shaping surface. Therefore, the flow of the contents discharged from the molding holes can be made continuous, but the amount of the contents discharged onto the shaping surface is greatly influenced by a length of an operation time when pushing down the inner plate. Accordingly, there is room for improvement regarding the shaping precision of the molded object.
  • the present invention has been made in view of the above problems, and it is an object of the present invention to provide a discharge container in which a fixing member is able to be easily detached from a container main body, variation in a discharge amount of contents discharged onto a discharge surface at respective positions is able to be minimized and a molded object is able to be formed on the discharge surface (shaping surface) with high precision while operability is improved.
  • the present invention proposes a discharge container according to the claims.
  • a discharge container capable of easily separating a fixing member from a container main body, minimizing variation in a discharge amount of contents discharged onto a discharge surface at each position and forming a molded object on the discharge surface (shaping surface) with high precision while improving operability.

  • FIG. 27 shows a state in which the conversion mechanism 236 is deployed in the circumferential direction.
  • the guide protrusion portion 255a includes a first vertical surface 255b which extends in the direction of the container axis O, and a first inclined surface 255c which gradually separates from the first vertical surface 255b toward one side in the circumferential direction as it goes upward from a lower end portion of the first vertical surface 255 b, and the guide protrusion portion 255a is formed in a substantially triangular shape which protrudes downward.
  • a lower end of the first vertical surface 255b and a lower end of the first inclined surface 255c are connected by a curved surface 255d protruding downward.

  • An upper end portion of the second inclined surface 232c is a curved surface 232d protruding upward.
  • the sliding protrusion portion 232a is smaller than the guide protrusion 255a as a whole and is formed in a shape approximately similar to that of the guide protrusion portion 255a.
  • An angle formed by the first vertical surface 255b and the first inclined surface 255c and an angle formed by the second vertical surface 232b and the second inclined surface 232c are the same as each other.
  • Rotation of the inner plate 215 in the clockwise direction (to the other side in the circumferential direction) with respect to the container body 202 in a plan view is allowed by the first inclined surface 25 c and the second inclined surface 232c. Further, rotation of the inner plate 215 in counterclockwise direction (to one side in the circumferential direction) with respect to the container body 202 in a plan view is restricted by the first vertical surface 255b and the second vertical surface 232b and by the upward pushing force applied to the inner plate 215 by the spring 253.
  • the sliding protrusion portion 232a, the guide protrusion portion 255a, and the spring 253 constitute a ratchet mechanism which allows the inner plate 215 to rotate about the container axis O only in one direction with respect to the container body 202.
  • the ratchet mechanism may be formed to allow clockwise rotation of the inner plate 215 with respect to the container body 202 in a plan view and to restrict counterclockwise rotation thereof.
  • FIG. 26 is a plan view of the fixing member 213, and a shape of the inner plate 215 seen downward from a cutting line A-A shown in FIG. 24 is indicated by an alternating two-dots-dashed line.
  • a plurality of guide protrusion portions 255a are formed on the inner circumferential surface of the external conversion cylindrical portion 255 at regular intervals in the circumferential direction. Therefore, a relief portion 255e is provided on the inner circumferential surface of the external conversion cylindrical portion 255 to avoid the guide protrusion portion 255a.
  • the relief portion 255e is disposed adjacent to the guide protrusion portion 255a in the circumferential direction.
  • the width of the relief portion 255e in the circumferential direction is larger than the width of the sliding protrusion portion 232a in the circumferential direction. Therefore, in a state in which the sliding protrusion portion 232a is located in the relief portion 255e, a space in the circumferential direction is generated between the sliding protrusion portion 232a and the guide protrusion portion 255a. As a result, when an excessively large rotational force is applied to the inner plate 215, for example, the sliding protrusion portion 232a continuously crosses the plurality of guide protrusion portions 255a in the circumferential direction, and thus it is possible to prevent the contents from being continuously discharged.
  • the plurality of sliding protrusion portions 232a are formed on the outer circumferential surface of the internal conversion cylindrical portion 232 at regular intervals in the circumferential direction.
  • the number (four in the shown example) of sliding protrusion portions 232a is the same as the number of guide protrusion portions 255a.
  • the number of sliding protrusion portions 232a may not be the same as that of the guide protrusion protrusions 255a and, for example, may be less than the number of guide protrusion portions 255a.
  • the inner plate 215 In the initial state before the operation, the inner plate 215 is located at the standby position shown in FIG. 24 .
  • the exterior portion 214 When the contents are discharged, the exterior portion 214 is rotated from the initial state around the container axis O toward the other side in the circumferential direction with respect to the container body 202.
  • the inner plate 215 rotates integrally with the exterior portion 214 around the container axis O with respect to the fixing member 213, and the first inclined surface 255c and the second inclined surface 232c are brought into contact with each other in the circumferential direction.
  • the sliding protrusion portion 232a moves down along the first inclined surface 255c as indicated by an arrow M1 in FIG. 27 . Therefore, the inner plate 215 moves down against the upward pushing force of the spring 253, and the locking portion 235 formed on the inner plate 215 moves down the stem 203a, and the diffusion chamber 234 is formed between the inner plate 215 and the exterior portion 214.
  • the contents discharged from the upper end portion of the stem 203a are supplied to the diffusion chamber 234 through the communication hole 233.
  • the contents are discharged upward from the communication hole 233, supplied to the core body 225, flow on the outer circumferential surface of the core body 225 in the direction of the container axis O, and are held by the core body 225.
  • the contents are held by the core body 225 to form a circular shape centering on the core body 225 in a plan view.
  • the contents supplied into the diffusion chamber 234 diffuse in the radial direction and are supplied from the supply surface 228 to the plurality of molding holes 226.
  • the contents that have passed through the plurality of molding holes 226 are discharged onto the shaping surface 227 to form a plurality of shaped pieces, and thus the respective shaped pieces are combined to form the molded object.
  • the sliding protrusion portion 232a When the exterior portion 214 is further rotated, as indicated by an arrow M2 in FIG. 27 , the sliding protrusion portion 232a reaches the lower end portion of the first inclined surface 255c of the guide protrusion portion 255a, climbs over the lower end portion in the circumferential direction, and reaches the relief portion 255e. Since the upward movement of the sliding protrusion portion 232a is allowed in the relief portion 255e, the inner plate 215 is moved upward to the standby position by the upward pushing force of the spring 253. Therefore, the locking of the stem 203a by the locking portion 235 is released, the stem 203a moves upward, the discharge of the contents from the stem 203a is stopped, and the contents in the diffusion chamber 234 are pushed out to the shaping surface 227. Further, when the contents are discharged again, the above-described action is repeated by performing the operation of rotating the exterior portion 214 again, and thus the contents can be repeatedly discharged.
  • the discharge container 201 of the embodiment it is possible to discharge the contents from the stem 203a and to stop the discharge to restore and displace the inner plate 215 to the standby position by rotating the exterior portion 214 around the container axis O with respect to the container body 202.
  • the receiving portion 254 for receiving an elastic force of the spring 253 extends toward the inside in the radial direction from the inner cylindrical portion 222 fixed in the annular concave portion 218 of the top wall plate 217, and the external conversion cylindrical portion 255 including the guide protrusion portion 255a extends upward from the inner circumferential edge of the receiving portion 254. Due to such a constitution, since the rigidity of the receiving portion 254 and the external conversion cylindrical portion 255 is increased and deformation or displacement of the external conversion cylindrical portion 255 is minimized by the elastic force of the spring 253, it is possible to stabilize a positional relationship between the guide protrusion portion 255a and the sliding protrusion portion 232a.
  • the angle formed by the first vertical surface 255b and the first inclined surface 255c of the guide protrusion portion 255a and the angle formed by the second vertical surface 232b and the second inclined surface 232c of the sliding protrusion portion 232a are the same as each other. Therefore, it is possible to increase the contact area between the first inclined surface 255c and the second inclined surface 232c when the sliding protrusion portion 232a slides on the guide protrusion portion 255a in the circumferential direction. Thus, for example, when the sliding protrusion portion 232a and the guide protrusion portion 255a slide, both of the sliding protrusion portion 232a and the guide protrusion portion 255a are prevented from being worn so that the sliding of them can be stabilized.
  • the central axis of the inner plate 215 is prevented from rotating to become inclined with respect to the container axis O during the operation, and the inner plate 215 can be smoothly rotated with respect to the container body 202 without being caught by the container body 202.
  • the guide protrusion portion 255a has the vertical surface 255b extending in the direction of the container axis O
  • the sliding protrusion portion 232a has the vertical surface 232b extending in the direction of the container axis O. Accordingly, rotation of the exterior portion 214 and the inner plate 215 around the container axis O with respect to the container body 202 is allowed only in one direction, and the sliding protrusion portion 232a which has reached the relief portion 255e can be promptly moved upward by the upward pushing force of the spring 253. Therefore, it is possible to improve the operability when the exterior portion 214 is rotated with respect to the container body 202, and it is also possible to stabilize the speed and amount of the contents discharged onto the shaping surface 227.
  • the guide protrusion portion 255a has the curved surface 255d protruding downward, and the sliding protrusion portion 232a has a curved surface 232d protruding upward. Accordingly, the sliding protrusion portion 232a can smoothly climb over the guide protrusion portion 255a in the circumferential direction.
  • the sliding protrusion portion 232a is provided on the inner plate 215 and the guide protrusion portion 255a is provided on the fixing member 213, but the present invention is not limited thereto.
  • the sliding protrusion portion 232a may be provided on the fixing member 213, and the guide protrusion portion 255a may be provided on the inner plate 215.
